+
+	void deleteMembers(array $users, bool check_not_admin = false)
+		- delete of one or more members.
+		- requires profile_remove_own or profile_remove_any permission for
+		  respectively removing your own account or any account.
+		- non-admins cannot delete admins.
+		- changes author of messages, topics and polls to guest authors.
+		- removes all log entries concerning the deleted members, except the
+		  error logs, ban logs and moderation logs.
+		- removes these members' personal messages (only the inbox), avatars,
+		  ban entries, theme settings, moderator positions, poll votes, and
+		  karma votes.
+		- updates member statistics afterwards.
+
+	int registerMember(array options, bool return_errors)
+		- registers a member to the forum.
+		- returns the ID of the newly created member.
+		- allows two types of interface: 'guest' and 'admin'. The first
+		  includes hammering protection, the latter can perform the
+		  registration silently.
+		- the strings used in the options array are assumed to be escaped.
+		- allows to perform several checks on the input, e.g. reserved names.
+		- adjusts member statistics.
+		- if an error is detected will fatal error on all errors unless return_errors is true.
+
+	bool isReservedName(string name, int id_member = 0, bool is_name = true, bool fatal = true)
+		- checks if name is a reserved name or username.
+		- if is_name is false, the name is assumed to be a username.
+		- the id_member variable is used to ignore duplicate matches with the
+		  current member.
+
+	array groupsAllowedTo(string permission, int board_id = null)
+		- retrieves a list of membergroups that are allowed to do the given
+		  permission.
+		- if board_id is not null, a board permission is assumed.
+		- takes different permission settings into account.
+		- returns an array containing an array for the allowed membergroup ID's
+		  and an array for the denied membergroup ID's.
+
+	array membersAllowedTo(string permission, int board_id = null)
+		- retrieves a list of members that are allowed to do the given
+		  permission.
+		- if board_id is not null, a board permission is assumed.
+		- takes different permission settings into account.
+		- takes possible moderators (on board 'board_id') into account.
+		- returns an array containing member ID's.
+
+	int reattributePosts(int id_member, string email = false, string membername = false, bool add_to_post_count = false)
+		- reattribute guest posts to a specified member.
+		- does not check for any permissions.
+		- returns the number of successful reattributed posts.
+		- if add_to_post_count is set, the member's post count is increased.
+
+	void BuddyListToggle()
+		- add a member to your buddy list or remove it.
+		- requires profile_identity_own permission.
+		- called by ?action=buddy;u=x;session_id=y.
+		- redirects to ?action=profile;u=x.
